In 1511, the Assassin Ezio Auditore da Firenze traveled to Constantinople, and after learning about the prison from a book in Sofia Sartor's book shop, took to the sewers from an entrance in the side of the city's bordering walls to a secret prison outside of Constantinople. Once there, he traversed many freerunning obstacles in order to claim Vlad's sword from his coffin, a weapon once rumored to be able to defeat any foe.
